This patch-set created after Marek remarks on patch board: stm32mp1: Add tx_fifo_sz_array support http://patchwork.ozlabs.org/patch/1056452/
This serie convert the DWC2 to driver model and use it for the stm32mp1 boards.
USB device and cable connection tested on EV1 and DK2.
This serie superseded the Patrice patches: http://patchwork.ozlabs.org/project/uboot/list/?series=97121

Hi Patrice,
The second patch series doesn't apply cleanly anymore, could you rebase and resend so I can test this series?
Hi, Yes, I have many pending series for the next releases on stm32mp1 arch and
for the 2 baord ev1 and dk2.
So many conflicts.
I willl push a rebase this week, but you can use my downstream branch (based on v2019.04) with all the upstreamed patches, including the last one for USB; I have already solve the issues:
https://github.com/patrickdelaunay/u-boot/tree/v2019.04-stm32mp
Thanks Patrick (and apologies for the previous wrong name),
:-)
the reason I ask is I'm testing an rk3288 with the DM_USB_GADGET support enabled for it's dwc2 OTG controller. The controller still works without DM_USB_GADGET enabled, but it fails to enumerate any USB devices when it is enabled. Is there anything specific required apart from enabling DM_USB_GADGET?
=> usb start starting USB... scan end No controllers found =>
I just add CONFIG_DM_USB_GADGET
But I also need to add a alias "usb0"
arch/arm/dts/stm32mp157c-ev1-u-boot.dtsi
/ { aliases { gpio26 = &stmfx_pinctrl; i2c1 = &i2c2; i2c4 = &i2c5; pinctrl2 = &stmfx_pinctrl; spi0 = &qspi; + usb0 = &usbotg_hs; }; };
The alias 'usb0" is needed to selecte the correct sed number
drivers/usb/gadget/udc/udc-uclass.c
int usb_gadget_initialize(int index) udc-uclass.c: ret = uclass_get_device_by_seq(UCLASS_USB_GADGET_GENERIC, index, &dev);
I spent some time to found it.
PS: sequence number is defined by alias in UCLASS :
UCLASS_DRIVER(usb_gadget_generic) = { .id = UCLASS_USB_GADGET_GENERIC, .name = "usb", .flags = DM_UC_FLAG_SEQ_ALIAS, };
